Greg Jandl to SDL I did some digging, and I think I've found a better solution. By including some additional .m4 macros in the acinclude directory (http://www.gnu.org/software/autoconf-archive/ax_check_compiler_flags.html, http://www.gnu.org/software/autoconf-archive/ax_gcc_archflag.html and http://www.gnu.org/software/autoconf-archive/ax_gcc_x86_cpuid.html) then using the patch below (same as previous patch + one line change to configure.in), SDL will build correctly out of the box. The arch can then be overridden by --with-gcc-arch=<arch> (most will probably want to build with i686 there for general distribution) or --without-gcc-arch, to disable setting the arch all together. On my Atom netbook, I get -march=PentiumPro by default, which works great, as does --with-gcc-arch=i686.

SDL on Sony Playstation3
------------------------

Installation:
  First, you have to install the Cell SDK
  - Download the Cell SDK installer RPM and ISO images to
    a temporary directory such as /tmp/cellsdk.
  - Mount the image: mount -o loop CellSDK-Devel-Fedora_3.1.0.0.0.iso /tmp/cellsdk
  - Install the SDK installer: rpm -ivh cell-install-3.1.0-0.0.noarch.rpm
  - Install the SDK: cd /opt/cell && ./cellsdk --iso /tmp/cellsdkiso install

  You'll than need to install the SPU-libs
  - Run make ps3-libs && make ps3libs-install

  Finally, install SDL
  - Go to SDL-1.2/ and build SDL like any other GNU style package.
  e.g.
    - Build the configure-script with ./autogen.sh
    - Configure SDL for your needs: ./configure --enable-video-ps3 ...
    - Build and install it: make && make install


Todo:
  - Mouse & Keyboard support
  - On SPU-side the current scaler and converter restrictions are:
    - resolution has to be a multiple of 8 (will work on that)
    - scaler/converter only supports the YV12 and IYUV format
    - the scaler works only bilinear (lanzos would be nice)
  - Optimize the SPU-program handling on the PPE side
  - Integrate spumedia in SDL

Have fun!
